6N135V Optoisolator - Equivalent & Substitute Parts

Part Overview

The 6N135V is a high-speed optocoupler manufactured by Isocom Components 2004 LTD, designed for applications requiring galvanic isolation with a 5000Vrms isolation voltage rating. This 8-pin DIP through-hole component features a single-channel transistor output with base connection, operating across an industrial temperature range of -55°C to 100°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts may be required due to manufacturer availability, supply chain considerations, or specific compliance requirements in target applications.

Substitute Part Grouping Explanation

Substitute parts for the 6N135V are identified based on strict parametric equivalence across the following critical specifications:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor with Base (mandatory match)
• Current Transfer Ratio Range: 7% to 50% @ 16mA (mandatory match)
• Package / Case: 8-DIP (0.300", 7.62mm) (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Input Type: DC (mandatory match)
• Maximum Output Voltage: 20V (mandatory match)
• Maximum Output Current: 8mA per channel (mandatory match)
• Forward Voltage (Typ): 1.45V (mandatory match)
• Maximum DC Forward Current: 25mA (mandatory match)
• Operating Temperature Range: -55°C ~ 100°C (mandatory match)

All identified substitutes meet these electrical and mechanical parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

The 6N135 from Fairchild Semiconductor is parametrically equivalent to the 6N135V across all critical electrical and mechanical specifications. However, the following compliance and status considerations apply:

6N135V (Isocom Components 2004 LTD): Active product status with ROHS3 compliance. Suitable for applications requiring current RoHS certification and ongoing manufacturer support.

6N135 (Fairchild Semiconductor): Obsolete product status with RoHS non-compliance. This part should be selected only when legacy system compatibility is required or when RoHS compliance is not a design constraint. The obsolete status indicates limited or no ongoing availability from the manufacturer.

Selection between these parts must be based on compliance requirements, supply chain availability, and whether the application permits use of obsolete components.

Frequently Asked Questions (FAQ)

Q: Can the 6N135 from Fairchild be used as a direct replacement for the 6N135V from Isocom?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical isolation voltage (5000Vrms), current transfer ratio range (7-50% @ 16mA), output type (transistor with base), package (8-DIP), and operating temperature range (-55°C to 100°C). However, the Fairchild part is obsolete and RoHS non-compliant, whereas the Isocom part is active and ROHS3 compliant. Selection depends on compliance requirements and availability constraints.

Q: What are the critical parameters that determine substitutability for the 6N135V?

A: Substitutability is determined by: isolation voltage (5000Vrms), single-channel configuration, transistor output with base connection, current transfer ratio range (7-50% @ 16mA), 8-DIP through-hole package, maximum output voltage (20V), maximum output current (8mA), forward voltage (1.45V typical), maximum forward current (25mA), and operating temperature range (-55°C to 100°C).

Q: Are there any timing differences between the 6N135V and 6N135?

A: The Fairchild 6N135 specifies turn-on and turn-off times of 350ns each. The Isocom 6N135V does not provide timing specifications in the available data. Applications with strict timing requirements should reference complete datasheets from each manufacturer.

Q: What is the significance of the RoHS compliance difference?

A: The 6N135V is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations. The Fairchild 6N135 is RoHS non-compliant. Applications subject to RoHS requirements must use the 6N135V or equivalent compliant alternatives.

Q: Can both parts be used interchangeably in new designs?

A: The 6N135V is recommended for new designs due to its active product status and ROHS3 compliance. The Fairchild 6N135 should be considered only for legacy system maintenance or applications where RoHS compliance is not required.
